Anti-shock traverse structure

ABSTRACT

An anti-shock traverse structure includes a movable frame attached to the traverse and the movable frame extending elastic plates and the elastic plates have a respective up bent section to resiliently bias against a lower side of the tray. The present invention is easily fabricated and has a better effect of anti-shock so that the deficiency of the conventional anti-shock traverse structure of the loader for a disk such as longer fabricating time and worse anti-shock effect can be improved substantially.

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to a loader for a disk, and, particularly, to an anti-shock structure of the traverse in a loader.

[0003] 2. Description of Related Art

[0004] Referring to FIG. 1, a conventional loader for a disk includes a base 10 associated with a traverse 20 and a tray 30. The base 10 has a transmission device such as the Publish No. 420349 in the Taiwanese Official Patent gazette. The transmission device disclosed in the Publish No. 420349 can actuate the traverse 20 at an end thereof having a turntable 21 to move up and down so as to enter and leave the position of a disk being driven and to drive the tray 30 entering or leaving the interior of the loader. The traverse 20 further has an optical pickup 22 to read the data saved in the disk or write data into the disk. The traverse 20 is attached with a movable frame 23 and both sides of the movable frame 23 pivotally join with the base 10 with a side thereof having a side plate 231. The side plate 231 at a lateral side thereof extends two post inserted into a guide rail of the transmission device so that the side plate 231 can be moved up and down with the guide rail and the movable frame 23 with the traverse 20 at the end having the turntable 21 also can move up and down. The tray 30 provides a hole 31 corresponding to the moving area of the turntable 21 and the optical pickup 22.

[0005] Referring to FIGS. 2 and 3 in company with FIG. 1, the movable frame 23 at the upper end of the side plate 231 has two up projecting fixing plates 232 and the side plate 231 is actuated by the transmission device to move toward the tray 30 so as to allow the turntable 21 passing over the hole 31 of the tray 30 and rotating the disk as soon as the tray 30 moves into the loader and is placed over the base 10. Right at the time, the side plate 231 at the two fixing plates 232 biases against the two shock absorption pads 32 at the lower side of the tray 30 so that the two shock absorption pads 32 can absorb the energy generated from the traverse 20 swaying up and down during the turntable 21 rotating the disk and the up and down swaying of the traverse 20 can be reduced. Further, the two shock absorption pads 32 adhered to the lower side of the tray 30 contacting with upper ends of the fixing plates 231 allows the fixing plates 232 not touch the bottom of the tray 30 directly and result in generating noise.

[0006] The preceding anti-shock structure formed with the two fixing plates 232 and the two shock absorption pads 32 takes a lot of time because the two shock absorption pads made of foam material has to be adhered to the bottom of the tray 30 and the foam material itself provides less elasticity with unfavorable effect of shock absorption so that it is easy to loss the property of shock absorption after using a longer period of time so as not to reduce the swaying resulting from the traverse and the noise resulting from collision.

SUMMARY OF THE INVENTION

[0007] The crux of the present invention is to overcome the deficiency of the prior art such as taking much more time for fabrication and worse anti-shock effect.

[0008] Therefore, a primary object of the present invention is to provide an anti-shock traverse structure, which is easily made and provides better anti-shock effect.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0016] Referring to FIG. 4, a loader with a new anti-shock structure according to the present invention includes a base 40 associated with a traverse 50 and a tray 60. The traverse 50 has a turntable 51 and an optical pickup 52 and a movable frame 53 is engaged to the traverse 50. The movable frame 53 at two lateral sides thereof is pivotally connected to the base 40 and a side plate 531 thereof has a lateral side extending and fitting with two posts in a guide rail of a transmission device. Hence, the transmission device can move the movable frame 53 and an end of the traverse 50 at the side of the turntable side 51 up and down.

[0017] Referring to FIGS. 5 and 6 in company with FIG. 4, the anti-shock structure of the traverse according to the present invention is different from the conventional one shown in FIG. 1 in that the movable frame 53 of the present invention at the side plate 531 thereof extends two elastic plates 532, 533. The side plate 531 at the inner side thereof extends two joining plates 534, 535 and each of the joining plates 534, 535 at another end thereof is attached to another side plate 536. Each of the joining plates 534, 535 at the lower end thereof is connected to another joining plate. Each of the two elastic plates 532, 533 at the lower end thereof extends outward the two joining plates 534, 535 longitudinally with a up bent section 537, 538 respectively. Each of the up bent sections 537, 538 biases against a corresponding pressed spot 62 respectively at the bottom of the tray 60.

[0018] The two elastic plates 532, 533 and the movable frame 53 are integrally made of plastic material instead of two shock absorptions being adhered to the tray at the bottom thereof in the conventional anti-shock structure so that it is quite easy to be made. Further, the two elastic plates 532, 533 have an up bent section respectively with stronger elasticity so that a better effect of shock absorption can be obtained with a sound durability. Therefore, the present invention substantially improves deficiency of the anti-shock structure of the traverse on the loader such as longer fabricated time and worse anti-shock effect.
